From Middle English Atlantyke, from Latin Ā̆tlanticus, from Ancient Greek Ἀτλαντικός (Atlantikós, “Atlantean, of Atlas”), from Ancient Greek Ἄτλᾱς (Átlās), either from ἁ- (ha-, copulative prefix) + Proto-Indo-European *telh₂- (“bear, undergo, endure”) or of Pre-Greek origin.
Usually functions as a proper noun preceded by 'the' ('the Atlantic'). When used as an adjective, it describes things related to this ocean or the countries bordering it.
